measuring Investment in human capital formation an experimental analysis of Early life outcomes
National Bureau of Economic Research, 2013Co-Authors: Orla Doyle, Colm Harmon, James J Heckman, Caitriona Logue, Seong Hyeok MoonAbstract:The literature on skill formation and human capital development clEarly demonstrates that Early Investment in children is an equitable and efficient policy with large returns in adulthood. Yet little is known about the mechanisms involved in producing these long-term effects. This paper presents Early evidence on the nature of skill formation based on an experimentally designed, five-year home visiting program in Ireland targeting disadvantaged families - Preparing for Life (PFL). We examine the impact of Investment between utero to 18 months of age on a range of parental and child outcomes. Using the methodology of Heckman et al. (2010a), permutation testing methods and a stepdown procedure are applied to account for the small sample size and the increased likelihood of false discoveries when examining multiple outcomes. The results show that the program impact is concentrated on parental behaviors and the home environment, with little impact on child development at this Early stage. This indicates that home visiting programs can be effective at offsetting deficits in parenting skills within a relatively short timeframe, yet continued Investment may be required to observe direct effects on child development. While correcting for attrition bias leads to some changes in the precision of estimates, overall the results are quite similar.

Social Science Research Network, 2012Co-Authors: Caitriona Logue, Colm Harmon, James J Heckman, Orla Doyle, Seong Hyeok MoonAbstract:The literature on skill formation and human capital development indicates that Early Investment in children is an equitable and efficient policy with large returns in adulthood. Yet little is known about the mechanisms involved in producing these long-term effects. This paper presents Early evidence on the nature of skill formation based on an experimentally designed, home visiting program in Ireland targeting disadvantaged families - Preparing for Life (or PFL). We examine the impact of Investment in utero and up to six months of age on a range of both parental and child outcomes. Using the methodology of Heckman et al. (2010a), permutation testing methods and a stepdown procedure are applied to account for small sample size and the increased likelihood of false discoveries when examining multiple outcomes. The results show that the program impact is concentrated on parental behaviors with little impact on key domains such as birth weight or Early child development. This indicates that home visiting programs can be effective at offsetting deficits in parenting skills within a relatively short timeframe, yet continued Investment may be required to observe direct effects on child development.

estimating the technology of cognitive and noncognitive skill formation
Econometrica, 2010Co-Authors: Flavio Cunha, James J Heckman, Susanne M SchennachAbstract:This paper formulates and estimates multistage production functions for children's cognitive and noncognitive skills. Skills are determined by parental environments and Investments at different stages of childhood. We estimate the elasticity of substitution between Investments in one period and stocks of skills in that period to assess the benefits of Early Investment in children compared to later remediation. We establish nonparametric identification of a general class of production technologies based on nonlinear factor models with endogenous inputs. A by-product of our approach is a framework for evaluating childhood and schooling interventions that does not rely on arbitrarily scaled test scores as outputs and recognizes the differential effects of the same bundle of skills in different tasks. Using the estimated technology, we determine optimal targeting of interventions to children with different parental and personal birth endowments. Substitutability decreases in later stages of the life cycle in the production of cognitive skills. It is roughly constant across stages of the life cycle in the production of noncognitive skills. This finding has important implications for the design of policies that target the disadvantaged. For most configurations of disadvantage it is optimal to invest relatively more in the Early stages of childhood than in later stages.

interpreting the evidence on life cycle skill formation
National Bureau of Economic Research, 2005Co-Authors: Flavio Cunha, James J Heckman, Lance Lochner, Dimitriy V MasterovAbstract:This paper presents economic models of child development that capture the essence of recent findings from the empirical literature on skill formation. The goal of this essay is to provide a theoretical framework for interpreting the evidence from a vast empirical literature, for guiding the next generation of empirical studies, and for formulating policy. Central to our analysis is the concept that childhood has more than one stage. We formalize the concepts of self-productivity and complementarity of human capital Investments and use them to explain the evidence on skill formation. Together, they explain why skill begets skill through a multiplier process. Skill formation is a life cycle process. It starts in the womb and goes on throughout life. Families play a role in this process that is far more important than the role of schools. There are multiple skills and multiple abilities that are important for adult success. Abilities are both inherited and created, and the traditional debate about nature versus nurture is scientifically obsolete. Human capital Investment exhibits both self-productivity and complementarity. Skill attainment at one stage of the life cycle raises skill attainment at later stages of the life cycle (self-productivity). Early Investment facilitates the productivity of later Investment (complementarity). Early Investments are not productive if they are not followed up by later Investments (another aspect of complementarity). This complementarity explains why there is no equity-efficiency trade-off for Early Investment. The returns to investing Early in the life cycle are high. Remediation of inadequate Early Investments is difficult and very costly as a consequence of both self-productivity and complementarity.

the microeconomics of Early child Investment
Journal of Children's Services, 2006Co-Authors: Arnaud Chevalier, Claire Finn, Colm Harmon, James J HeckmanAbstract:This article illustrates the key findings from the economics literature on education Investment, in particular the findings focused on Early child Investment. The article shows the impact of Early Investment, particularly evidence from experimental programmes on later life outcomes such as labour market performance and societal position. It demonstrates how Investment in children is both an important Investment for the child but also an important tool for economic and social policy.
